"It was billed as the 'Ultimate Ladies' Night' but only 21 people showed up. Their manager came out looking frantic as the time drew closer to them going on stage and the room stood empty," a source told the paper.

"When he realised how small the crowd was they decided to push the show back by an hour. As they waited for the room to fill up, both Michelle and Zoe happily chatted to fans in the lobby.

"It was then that the girls told concert goers that Kerry had to pull out of the tour after she had taken ill before their gig in Mumbai six days ago."

Kerry had been performing with Zoe and Michelle in India previously – where they were billed as Atomic Kitten’s Kerry Katona, Liberty X’s Michelle Heaton, and former Pop Idol star Zoe Birkettt.

Atomic Kitten's management are said to be pursuing legal action against the promoter of the gig for falsely advertising the concert.

"The Mumbai concert was not nor ever was supposed to be an Atomic Kitten Gig and has been falsely advertised by the promoter to which effect we are currently pursuing legal action against," they said.

"This same promoter has then promoted another gig in Dubai once again falsely advertised as the girls where never even invited to attend to perform."

Mirror Online has contacted Kerry's representative for comment.

Earlier this year, Kerry Katona and Natasha Hamilton were forced off stage after rowdy revellers started chucking bottles at them.

The singers, who made up two-thirds of Atomic Kitten, had been performing at the Engine Shed in Lincoln when a group of men showed up – and at least one of them pelted the stage with food and bottles, according to eyewitnesses.

A source exclusively revealed to Mirror Celeb that the pair felt unsafe when the missiles started flying.

"They had a great show until a group of lads turned up and started throwing money and bottles. So they cut the gig short. The groups of lads responsible were promptly thrown out."

Kerry later tweeted her anger at being interrupted mid-performance and slammed the miscreants, writing: "Well that was fun!! What a shame when some young boy going through puberty thinks it's manly to throw bottles at girls!! #waiting4balls2drop ."

Natasha said she was "gutted" by what had happened and thanked fans for their support.

"Gutted that tonight's gig ended early, 2 all of u who came to see a good show, thank u 4 yr support but when it's not safe we have 2 leave x," she added.

Producer and DJ Guy Alderton, who was sharing a stage with the Kittens, apologised to fans for the disappointing end to the gig,

"I'm sorry, I was loving it too. People love to ruin things," he told one partygoer on Twitter.

Many of the Kittens fans begged Kerry and Natasha to come back, and one even called for the promotional night to be made female-only.

James Brooks, CEO of the University of Lincoln's Student Union, told Mirror Celeb that the Engine Shed has apologised to Kerry and Natasha.

"The Engine Shed is appalled by the behaviour that took place at last night's Atomic Kitten performance and apologises unreservedly," he said.

"We are sending flowers to Kerry and Natasha as a token of our regret and are investigating the incident as a matter of urgency.

"The students involved were immediately removed from the Engine Shed. The situation was dealt with swiftly and professionally by the Engine Shed staff with no further issues on the night."

He added: "A number of students have taken to social media to express their anger at the action of a few individuals and we are keen to emphasise this behaviour is not demonstrative of the majority of our students. Kerry and Natasha are big favourites in the city as the huge attendance at last night's show demonstrated."
